Structures

Defining Structures

Use the `structure` keyword to define data shapes.

    structure Point {
        x;
        y;
    };
    
    p = Point();
    p.x = 10;
    p.y = 20;
    

Constructors

You can define an initialization method named constructor.

    structure Point {
        x; y;
        function constructor(x, y) {
            this.x = x;
            this.y = y;
        }
    }
    p = Point(10, 20);
    

Inheritance

Structures can inherit fields and methods using extends.

    structure Shape { area; }
    
    # Calculated Parent Fields
    structure Square extends Shape(width * width) {
        width;
    }
    
    s = Square(5);
    print(s.area); # 25
    

Static Members

Use the static keyword for fields and methods belonging to the structure type rather than the instance.

    structure MathUtils {
        static PI;
        static function circleArea(r) {
            return MathUtils.PI * r * r;
        }
    }
    MathUtils.PI = 3.14159;
    

Dynamic Method Addition

Methods can be added to structures or instances at runtime using addMethod.

    structure User { name; }
    function sayHello() { return "Hello, " + this.name; }
    
    # Add to structure (affects all new instances)
    User.addMethod("hello", sayHello);
